+++ This bug was initially created as a clone of Bug #1650949 +++

It would be requested to have the option to modify the 'nfs_mount_options' in the [libvirt] section of the nova.conf during the overcloud deployment.

~~~
[libvirt]
# Mount options passed to the NFS client. See section of the nfs man page
# for details.
#
# Mount options controls the way the filesystem is mounted and how the
# NFS client behaves when accessing files on this mount point.
#
# Possible values:
#
# * Any string representing mount options separated by commas.
# * Example string: vers=3,lookupcache=pos
#  (string value)
#nfs_mount_options=<None>
~~~

I could not find this parameter within THT or the openstack-puppet modules.


Cheers,
Marc Methot

Verified by adding the following parameters to overcloud_deploy:

parameter_defaults:
  ComputeExtraConfig:
    nova::compute::libvirt::nfs_mount_options: "vers=3,lookupcache=pos"


After deployment we can see the values in the nova.conf on compute nodes:


[heat-admin@compute-0 ~]$ sudo docker exec nova_compute grep nfs_mount_options /etc/nova/nova.conf
#nfs_mount_options=<None>
nfs_mount_options=vers=3,lookupcache=pos
